Unable to create edge using create edge statement

[SaqlainHussainShah]

Here is my code `from nebula2.gclient.net import ConnectionPool
from nebula2.Config import Config

define a config

config = Config()
config.max_connection_pool_size = 10

init connection pool

connection_pool = ConnectionPool()

ok = connection_pool.init([('localhost', 9669)], config)

session = connection_pool.get_session('root', 'nebula')

SHOW SPACES

session.execute("SHOW SPACES")

CREATE SPACE

SPACE_NAME = "nba"
CREATE_SPACE = "CREATE SPACE IF NOT EXISTS nba(partition_num = 5)" # replica_factor not working because single system
session.execute(CREATE_SPACE)

SELECT SPACE

SELECT_SPACE = "USE {}".format(SPACE_NAME)
session.execute(SELECT_SPACE)

DESCRIBE SPACE

session.execute("DESCRIBE SPACE nba")

SHOW TAGS, SPACES

result = session.execute('SHOW TAGS')
print(result)

#CREATE PLAYER TAG
PLAYER_SCHEMA = "name string NOT NULL, age int"
CREATE_PLAYER = "CREATE TAG player({})".format(PLAYER_SCHEMA)
session.execute(CREATE_PLAYER)

CREATE TEAM TAG

TEAM_SCHEMA = "name string"
CREATE_TEAM = "CREATE TAG team({})".format(TEAM_SCHEMA)
session.execute(CREATE_TEAM)

DESCRIBE TAGS GIVES DETAILS OF TAG

result = session.execute('DESCRIBE TAG player')
print(result)

CREATE TAG WITHOUT A PROPERTY

session.execute('CREATE TAG property_free()') # Without using () at the end was not creating this TAG

SHOW TAGS

session.execute("SHOW TAGS")

#DELETE A TAG
DELETE_TAG = "DROP SPACE nba"
session.execute(DELETE_TAG)

CREATE EDGE TYPE

CREATE_EDGE = "CREATE EDGE follow(degree int)"
session.execute(CREATE_EDGE)

session.execute("SHOW EDGES")

CREATE_EDGE = "CREATE EDGE serve(start_year int, end_year int)"
session.execute(CREATE_EDGE)
session.execute("SHOW EDGES")

session.execute("DESCRIBE EDGE serve")`

The output for session.execute("SHOW EDGES") and session.execute("DESCRIBE EDGE serve") is ResultSet(None)

The reason for not creating edges is that In my code I am deleting the space before creating edges. that was my mistake
